Buddhism Already Corrupted when brought to Japan.
This sixth century Buddhism in Japan was not the army with banners, which was introduced still later with the luxuriances of the fully developed system, its paradise wonderfully like Mohammed's and its over-populated pantheon. It was, however, ready with the necessary machinery, both material and mental, to make conquest of a people which had not only religious aspirations, but also latent aesthetic possibilities of a high order. As in its course through China this Northern Buddhism had acted as an all-powerful absorbent of local beliefs and superstitions, so in Japan it was destined to make a more remarkable record, and, not only to absorb local ideas but actually to cause the indigenous religion to disappear.
Let us inquire who were the people to whom Buddhism, when already possessed of a millenium of history, entered its Ultima Thule in Eastern Asia. At what stage of mutual growth did Buddhism and the Japanese meet each other?
Instead of the forty millions of thoroughly homogeneous people in Japan—according to the census of December 31, 1892—all being loyal subjects of one Emperor, we must think of possibly a million of hunters, fishermen and farmers in more or less warring clans or tribes. These were made up of the various migrations from the main land and the drift of humanity brought by the ocean currents from the south; Ainos, Koreans, Tartars and Chinese, with probably some Malay and Nigrito stock. In the central part of Hondo, the main island, the Yamato tribe dominated, its chief being styled Suméru-mikoto, or Mikado. To the south and southwest, the Mikado's power was only more or less felt, for the Yamato men had a long struggle in securing supremacy. Northward and eastward lay great stretches of land, inhabited by unsubdued and uncivilized native tribes of continental and most probably of Korean origin, and thus more or less closely akin to the Yamato men. Still northward roamed the Ainos, a race whose ancestral seats may have been in far-off Dravidian India. Despite the constant conflicts between the Yamato people who had agriculture and the beginnings of government, law and literature, and their less civilized neighbors, the tendency to amalgamation was already strong. The problem of the statesman, was to extend the sway of the Mikado over the whole Archipelago.
Shintō was, in its formation, made use of as an engine to conquer, unify and civilize all the tribes. In one sense, this conquest of men having lower forms of faith, by believers in the Kami no Michi, or Way of the Gods, was analogous to the Aryan conquest of India and the Dravidians. However this may be, the energy and valor displayed in these early ages formed the ideal of Yamato Damashii (The Spirit of unconquerable Japan), which has so powerfully influenced the modern Japanese. We shall see, also, how grandly Buddhism also came to be a powerful force in the unification of the Japanese people. At first, the new faith would be rejected as an alien invader, stigmatized as a foreign religion, and, as such, sure to invoke the wrath of the native gods. Then later, its superiority to the indigenous cult would be seen both by the wise and the practically minded, and it would be welcomed and enjoyed.
